What this shows Purewine's Innovation Score is 31.8/100 (39th percentile of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Purewine?

Each dot is one of Purewine’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Purewine’s own 14.3 claims/patent is at or below the 15.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Purewine's grants concentrate

Purewine Inc. is a focused PatentsView assignee: 7 CPC subclasses with 57.1% of grants classified under C12H (Pasteurisation, Sterilisation, Preservation, Purification, Clarification OR Ageing OF Alcoholic BEVERAGES; Methods FOR Altering THE Alcohol Content OF Fermented Solutions OR Alcoholic Beverages). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2017. By volume, Purewine sits between Pumptec, Inc. and Q-bot Limited.

Purewine's three-year grant acceleration

Purewine Inc. shows 2 grants in 2022–2024 against only 2 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
